low hot water pressure in 2005 winnebago Class A

[jhp]

very low pressure - any suggestions?

[lwasouth]

My problem was on an Adventurer. The problem with the hot water was the check valve on the hot water tank. The internal portion of the valve broke and closed off the water entering the tank (Thus no water leaving the tank)
I removed the check valve, removed it's internal part and reinstalled it. Some say it is needed but everything worked well without it

If the valve does not work it will not blow off excess pressure but may rupture plumbing or tank

You have to read what I wrote! We are not talking about the pressure relief valve on the front of the tank.
The problem is the "one Way" check valve on the back of the tank on the cold water line (Water in) Nothing to do with the pressure relief valve that relieves excess pressure. This is why I don't like to answer questions, because people don't read the answers

I did read your answer and I agree with you, as I had a very close experience with my 2002 Adventurer a few years ago.

It is a major pain to get at that valve (mine is in the rear) (of the water tank that is ) and I removed the valve that failed, as apparently yours did too.

I believe that the valve is useful for winterization so that the water heater isn't filled with the pink koolaid, as we call it here in the north.

However, I use low pressure compressed air and use the koolaid dollars saved for replacement water heater one way valves.

I in no means endorse this method for others, and I hold myself harmless for any and all money saved by anyone else.

I believe you are now talking about the 'bypass valve' which I don't believe is a one way valve

No he is talking about the check valve on the output line on the rear of the tank. Mine just failed only it shut off so I had no hot water flow at all. This is a valve that fails often so I would say that is your problem.

I don't believe a 'check valve' is used in the winterization process to keep 'pink stuff' out of the wh. I believe that is the bypass valve. But I believe that the valve he is talking about may be a check valve in the output line. Because I am such a dummy- what purpose does a check valve do in that position. Wouldn't the wh stay pressurized from the pump or cg supply and prevent water from back flowing through that outlet? If water did empty out of the wh wouldn't it be better to have back flow so that you wouldn't be trying to heat an empty tank. Inquiring minds and all that...

Was in a Winnie just this afternoon, the owner's complaint was "No water flow at the sink" (I'm an electronics tech so went there to deal with his sat TV system, Since I'm not a pro. he got off cheap... That was a job, he'd disconnected everything and taken one wall plate (the problem) off the wall, in so doing a cable came loose and was hidden IN the wall,, Had to fish it out, bring it back through the wall to the plate, and hook it up.. This was the most work I've done on any "TV NOT WORKING" job yet, (I do one a year normally, 2 this year).... Then I had to go back and replace a fitting.

Back to water.. Just to check, I disconnected the MOEN head from the hose (it's a pull out faucet in the kitchen)

The moern Moen head has a flow restrictor device in it.. i was working,, quite well in fact. It was restricting the flow all the way to ZERO.

I handed the head to his wife, She fixed it. 3

I had this problem in my adventurer. I cleaned all the screens at the faucet heads and the screen at the pump. All had build up of what looked like calcium. The hot water now works great. Hope this helped. Also found that the main sink faucet sometimes does not open the hot side if I put it on fast. I open the one lever faucet in the center then move it to the hot side and it works fine, just a thought.

More information would be nice. Is it on both Hot & cold, is it while only hooked up to City Water or while using the Water Pump, is it at every faucet or only certian ones????
